The magnetic force acting on a particle with charge "Q", moving with a velocity "V" in the regiion where there is a magnetic field, B. is given by the cross product between V and B + Fm = Q.Vx B m Let an electron be traveling with a velocity VQ =(3i1j + 2k). 10 5 m S In a region of space where the magnetic field is Bm = (5-i+ 4j + 6k).T 11. Find the magnetic force acting on the electron expressed in i,j,k format 12. Find the magnitude of the magnetic force acting on the electron 13. Find the angle between. and B 14. Find the angle between. Fm and B 15. Find the angle between. Fm and V 16. Prove the statement; The magnetic force never does work 17. Prove the statement; The magnetic force will only change the direction of the velocity, not the speed
